To all whom it may 'concer/n.

`State of Illinois,

Beit known that I, Sumar DANE Poom,

.Y "..aivcitizen of the United States, residing at in the county of RockIsland and Moline have invented certain new and useful Improvements inCultivators, of

.which the following is a specification, referi ence being had thereinto the accompanying drawing.

. This invention relates-*to improvements in l fcultivators.

The novel features of construction and f arrangementy can be employed1x1-earth working tools of any of a number of styles of this generalclass. lThe matters of improve. 1 ment, however,

are particularly well 'adapted for use in cultivators of the sortemployed in 4culvivating orchards. y The object of the invention is toprovide a-.construction in which the tool-carrying element shall beadjustable independently r ofthe supporting and transporting element;

in which the heavier work of lifting and adjusting the tools can beaccomplished by the force of the draft, or, when desired, by

-' 'a minimum of manual labor, by which sevformly in L lbeyond thesupporting elements, for purposes to be setforth.

A Figure 1 is a plan view of a cultivatingv mechanism embodying myimprovements.

Fig. 2 is a side elevation of the same. Fig. 3

is a rear elevation. Y Fig'. 1- is a detail 'View showing in sideelevation steering devices of a diiierent kind than are shown in Figs. 1

and 2. Fig. is a plan View showing the machine with the tool framefitted withthe detachable lateral extensions.

1 is an axle upon which are mounted the wheels 2, 2.

3, 3 indicate upright bars .which are carried upward a suliicientdistance to conveniently support a drivers seat and which y' may berformed 'of one 'length'ot metal suitsupported ably bent. At their lowerends they are ign the axle 1 by means of clips 4, 4. ,in theba'r'sf, 3there extend Specification of Letters Patent.'

horizontal bars 5, 5, which.`are bent inward at 6, 6, and at their frontends are secured to a vertical casting or bearing piece 7.

8, 8 are uprights or vertical barswhich are secured to the bars 5, 5 andextend downward 'therefrom to a long horizontal crossbar 9. This bar isat its ends connected to the axle by horizontal arms 10, 10, these-being secured to brackets or clips 11 Aat their rear ends. v A v 12 isa brace bar or tie-bar interposed between the top kbars 5, 5 and securedthereto. j The workingrame, or frame which ear'- ries the tools, is'constructed as'follows: 13

`is a long rear cross-bar connectedto for- Wardly extending bars 14,14,' the latter having their front parts 15 converged or' bent inwardtoward the central longitudinal plane. vPreferably the cross-bar 13andthe longitudinally arranged bars 14, 15, are all formed from'a singlebar of metal-suitablyr .shaped by bending. 16, 16 are longitudinallyarrangedv bars which at their front ends are flanged, and bolted, as at17, to the bars 15. At their rear ends they are hanged and secured at18to the cross bar 13. 19 are crossy bars interposed between the side bars14: Iand the intermediate bars 16. Tool supporting bars 21, of anysuitablel number,

are arranged `longitudinally in the working frame. By suitably bendingthe` bars, as shown at 13a, one can be utilized to support more than vasingle tool and hold one tool out of the longitudinal line of another.Bars 16 are also utilized to support tools, as shown in the drawings.

The partsof the longitudinal bars which carry the tools are so spaced inrelation to each other that the wheels can be placed either close toether or farther apart, as may be desired. hus in Fig. 1 and others, thewheels are shown relatively close together, each being situatedbetweenone of the bars 16'and bar 21; whereas in Fig. 5 the'wheels `are mounted'at other points on the axle, in

the spaces between the outer bars 14 and the next -adJacent longitudinalbars 21. In either case the wheels ,are surrounded, hori- `zontallybyframe work adapted to carry, on

its Llatera.lly"projecting parts,'tools in'longii Patented May 25,'1915.

tudinal planes outside of 'the wheel plane, as well as carry toolsbetween the wheels.

The other parts of the working frame or tool frame consist of twosimilar frame sections each of which has a rear bar 13b and framestructure can be employed, that is, the

larger central part andthetwo end sections. But under many circumstancesit is found that but one of them need be present, and at such times theotherA can be removed. vIt will be seen that with a prbvision of thischaracter taken in connection wlth the provision for changing theposition of vthe wheels, there is a wide range in respect to the extentto Awhich a tool carrier can -be projected laterally beyond eitlyer` ofthe wheels.

22, 22 are bars diverging and extending backward from the casting 7 towhich they are secured at their front ends. At their' rear ends they aresecured to the cross bar 9 ofthe supporting wheel frame. supporting andsteering device is'provided consisting of the caster wheel 23, its yokecarrier fill and vertical spindle 25. The spindle is mounted in thetubular bracket casting 7. p The working frame that has been abovedescribed is supported on and carried by the wheel frame, but is movablyconnected thereto. At each side of the machine there are two'parallellink Ibars 26, 27, each pivota'lly connected at one end to a side bar ofthe wheel frame, and pivotally connected at the other end to a side barof the tool frame or working frame 14. The pivotal attachments for.these links consist of plates orv lugs 28 which are rigidly fastened tovthe side bars of the frames. At the front end of the working frame thereis a forwardprojectinglframe extension 30. 32 indicates a strap frameextending forward and downi to guide the machine. v Y

vices also are adapted to permit the tool ward from vthe upper end ofthe spindle 25, to `'which it ispivotally attached, and it carries aloop 33 through which passes the bar or draft link 31, the latter beingsecured by a vertical pivot to the frame extension 30 and being capableA of moving longitudinally, to a limited extent, forward andbackward through the loop. With this construction,

the lateral swinging of the link 31 under the action f the draft istransmitted to the strap frame 32 which is thus caused to turn thespindle 25 of the steering wheel 28 so as frame to rise and fall\freely'for the strap frame 32 swings forward'and upward "in" A front parallellink hars 26, 27, insure These steering de-f unison with the tool frameas it is `moved upward and forward on the parallel links 2c, 27.

When the machine is to be used on hillyr ground, I prefer to do thesteering by means of a pole or tongue 41 such as shown in Figs. l and 2,it being possible with the tongue to keep the machine from running ontoythe heels of the horses. A seat 34 for the driver is mounted on theupright frame part'.v

'lo enable the'driver when in his seat to adjust the working or toolframe up and down and'to lock itin adjusted position the fol# lowingdevices are provided. 36 is a'transverse rock shaft mounted on theframebars 5, 5 and carrying at its lends crank arms 351' the shaft 3G andprovided with a locking device 39 which coperates with the notchedsegment 38. By swinging the hand lever the tool frame can be raised andlowered y in horizontal parallelism and locked in the 1 desiredposition. By providing the double crank arm and link connection, bothsides of the tool frame are very firmly supported so that the tendencyfor one side of the frame to bevdrawn deeper than the other is.thoroughly overcome. Such a tendency is especially noticeable when onlyone of the side extensions of the tool frame is employed.

The tools `are secured to the adjustable i frame in such manner thatthey lie some on y 10o Y f that is to say, a set of tools isfrelativelyfarf Y one transverse line, and some on other lines,

ther forward, and another set or other sets, are relatively fartherbackward. When. the tool frame is constructed and related a'id connectedto the wheel frame in the manner described, thesets of tools are allkept in predetermined l'positions relative to each u other and tothesurface of the grou d. rllhe front tools sh'all rise and fall in hizontal parallelism with the rear ones, an Variation inthe depth ofcutting is avoided.

at the w The wheels are secured in place vlongitudinally of the .aXle bymeans ofpcollars' ,40,- 115i.

which are adapted to'be secured to the axle at either lof several placesalong it. At times it is desirable to have the wheels close tbi f getherand equally distant respectively from the adjacentuends ofI the toolframes, as

shown by broken' lines ,in Fig. 1; at vothers it is preferable to havethem respectively near the side bars though equi-distant therefrom;

.while in still other cases it is desirable to have both'wheelsrelatively nearer onfe end' of the frame than the other. that is to'say,to

have a considerable part-of the frame project atone sidesome distancebeyond the adf jacent Wheel, while the opposite wheel is situated nearits side bar. Each of these'relav tive positions can be qulckly secured"1n the lr1-f1.: soustraction, as it is onlynecessary f to' withdraw theremovable cotters which sei f cure the axle 1 in the holders at l1, andalso the cutters from the set collars a() for the wheelhuhs, after whichthe collars can be reset at different places to hold thewheels in any ofthe above described relative positions. i 1

" orchards orplots of ground where 1limechanismsuch 'as herein shown isparticularly well `adapted for cultivating bushes for trees are growing,especially' trees with vtime uniformly at the two ends, beyond the lbnch relatively close to the ground.

Thev tool frame can he caused to project more or less at each end, andat the same wheels, so'that the projecting ends can carry ground 5* toproject to a still greater extent at one end fin order that the tools atthat end may @X tend farther under overhanging parts, the

"-"fidraft mechanism, and the drivers s119190 being at all times invertical planes outside of such overhanging bodies. The construction ofthe parts of the two frames 'which i l ,k '1" have described enables meto keep the opsyerative parts in lowI horizontal planes and' A" Thedraft isv transmitted directlyvto the tool framework, rearsupportmgwheels, a front provide a mechanism of great strength;

. l, fraind'th'e wheel frame constituting merely fa supportingv andcarrying'structure. The

tools can be' of any of the several sorts used i rcuitivator hoes, orthe wider scraping shov" n plowlilre tools that are frequently used. Til

` 1n the way described it can be utilized to lift Y 4'.llgthe frame andtools out of thevground, such on machines of this general class,ordinary els, or the e draft of the team being applied .lifting by thepower ofthe draft commenc- .f Y ing Vas soon as the operator releasesthe de- Y :tentBQ from the segment 38.

By means of the lever and its lock, the tool fraone andthe tools can befastened rigv ,idly in any working i that may be desired. lVith amachine conposition, vertically,

f. `st'ructed in the way describedthe shovels ycan be held at apredetermined uniform 59 depth and be prevented from entering the groundy at one side of the machine more deeply than at the other, even whenthe wheels are so placed in relation to the frames that the tool frameoverhangs at one end or extends considerably farther-be- ].yond theadjacent wheels than it extends aV the other endbeyond the oppositewheel. lhefshovels .at the overhanging or projectr ying end areprevented from sinking beyond Y 4the depth desired, which is uniform forall lthe tools.

lt. will be seen that 1 provide amain frame which is -held unifornilyatall times in relation tothe surfaoe of 'the ground;

secondly, al'vertically movable tool frame Linosa? which is heldpositively, after adjustment, 'l

25) which is vibratable horizontally relatively to the other two frames,but not movable, in ordinary use vertically in relation to the mainframe. For certainkinds of cultivation a mechanism of this sort is muchmore advantageous than arethose wherein .the frame elements (includingthose mounted directly on the ground wheels, and those which areconnected to the tool) are so ar- -frame orsupport (the yoke 24 andspindle f l ranged that they can rock around the axis of the wheels whenat ground wheels in the present machine are fixed on transverse lineswhile the front wheel, as aforesaid, is adapted to swing laterally, andalthough connected to the main frarneit is indirectly connected to thevdraft devices in such way that the forward force of the draft ispractically all taken, primarily, by the tool frame, the transmission ofdraft forceto the main frame being effected throughthe' tool frame.
